Patients may start to feel less anxious and experience improvement in things like sleep and some of their other anxiety symptoms. For patients who take benzodiazepines -- these are the Xanax (alprazolam) or Klonopin (clonazepam)-type drugs -- relief of anxiety tends to be more rapid, often occurring in hours or days.ntidepressant medications -- the so-called fluoxetine or Prozac-like drugs -- start to work over a period of weeks -- two, three weeks.
Antidepressants such as Celexa may take several weeks, perhaps even more than a month, to start working. In most cases, the physical symptoms of depression (such as pain or changes in sleep patterns) will improve first, sometimes within the first few weeks of treatment. It usually takes at least four to six weeks before significant changes in mood occur. For Celexa to work properly, you have to take it as prescribed. The antidepressant will not work if you take it differently than your healthcare provider prescribes. The medication should be taken at the same time each day to maintain an even level in your blood.
